Web6 jul. 2024 · What do we look for in RF/microwave filter performance? The standard lumped-element parameters apply, such as center frequency, 3-dB bandwidth, attenuation within and outside of the passband, selectively, rolloff, and passband/stopband ripple, to cite just a few. Hello, distributed filters Bands of frequencies in the microwave spectrum are designated by letters. Unfortunately, there are several incompatible band designation systems, and even within a system the frequency ranges corresponding to some of the letters vary somewhat between different application fields. The letter system had its origin in World War 2 in a top-secret U.S. classification of bands used in radar sets; this is the origin of the oldest letter system, the IEEE radar bands. One set of microw…
